PetDressUp

Allows you to control-click to preview a mount/minipet. Works with both item and spell links.

This mod will not work for mounts/minipets which you have not yet encountered (you can only encounter the mounts by owning it, or by visiting the stables where an NPC version of the mount should stand, I may have a way to fix this for a future version).

but anyway just quickly looking at the source code, mine creates substantially less tables, and is in general smaller (and imo better) code wise. Also mine if AddonLoader is installed will only load when used.
